Following on from our previous piece on how to stop condensation on single glazing, you’ll find out here how to prevent it from building up on all types of window. Just because you have double or triple glazing doesn’t mean you’re immune to the occasional bout of condensation. Knowing how to stop condensation on windows isn’t too difficult and it doesn’t often require you to spend any money. It can just need a little care and attention.

Find the source before settling on how to stop condensation on windows

The fact that your windows are condensing up doesn’t necessarily mean they’re poor quality. It may actually mean that your home isn’t insulated or ventilated effectively. Before you take any of the following five easy steps into consideration, you should first detect what the source of the condensation is. You won’t know how to stop condensation on windows before you’ve figured that out.

Keep your home well ventilated

As long as it isn’t too windy, wet or cold to keep windows open, you should try opening them every day. The warmer air from inside will be able to escape rather than hit the window and start forming condensation. While double and triple glazed windows have a high U value, meaning they’re more energy efficient, over time they can cease being as effective as they were to start with.

Fit an extractor fan in bathrooms and kitchens

It’s inevitable that condensation will form on your windows in wet rooms. Even if you open the windows and have an extractor fan fitted, a small amount may still form on window surfaces. However, a small amount shouldn’t cause any harm and will evaporate back off again in a short period of time.

Tie back curtains and open blinds

This will allow air to circulate around the room more freely. The more that air can circulate, the less likely it is that condensation will form. It’s always a good idea to keep furniture a few centimetres away from walls for exactly the same reason. This will prevent the build-up of mould and damp issues. Knowing how to stop condensation on windows can be entirely cost-free.

Seal any cracks or faults in your walls

If you can clearly see any faults in the structure of your house, you should make sure they don’t follow through to outside and seal it as soon as possible. This can be a huge source of moisture getting into the air and plastering your windows in condensation overnight. If your windows are regularly misted up each morning, this could be the reason why.

Replace your windows if all else fails

If your windows are getting a bit old and have stopped being as energy efficient as they were when you bought them, it may be time to get some new ones fitted. This should hopefully only be a last resort. As long as you’re vigilant with how much additional moisture you release into the air, your windows should avoid the worst of the possible damage. Never underestimate the importance of putting lids on pans while cooking, turning extractor fans on and opening windows. The simplest and cheapest methods are often the most effective.
